Just back from a trip to SE Asia and along the way my D7000 exhibited some strange behavior. The camera seemed to have a mind of its own when numbering folders. Even if I selected a particular number for the shooting folder the camera would increment to a new folder number on its own. This happened on a number of occasions. It also made a strange jump in the file numbering. It went from about 3900 to 8800 for no apparent reason.
